I have 3 view controllers. First is MainViewController.

In this MainViewController has custom table view cell as FoodCell class with two property as name and price.

I instantiate this objects in MainViewController and when tap to table view cell this objects pass to popup DetailViewController which is not table view it is only View with labels(foodName and foodPrice labels) and AddToBasket button.

And finally I want to pass this class objects from popup DetailViewController to MyCartViewController. MyCartViewController is my final scene for show the foodNames and foodPrices objects.

(e.g. MainViewController is my food menu list. DetailViewController is my selected foods list.MyCartViewController is my market bag. )
